I know TinyWall and I believe Windows Firewall Control use .NET. Are there any add ons to tweak Windows Firewall that do not use .NET?
Why not use .NET ? It is already integrated in the operating system. Windows Firewall Notifier is also developed under .NET. I don't think you will find an alternative that uses only native code.
TinyWall works with the already installed 3.5 on W7. WFC 4 you have to download net 4. Gives me a slight slow-down. Good luck!
NET. up to 4.5., supports the latest applications. There's no reason not to get it - given its Microsoft's universal program runtime.
